Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning enhancer composition and a cleaning composition used together with a cleaning agent to enhance the cleaning power and the like, and more particularly, to a hotel or restaurant cook in the field of linen supply and the like. Suitable cleaning enhancer compositions and cleaning compositions for washing linens such as clothes and cloth and mop cleaning in the field of dust control, as well as shirt pillowcases in the field of laundry and hotel pillowcases in the field of linen supplies The present invention relates to a suitable powder detergent composition for washing white matter.

[0002]

2. Description of the Related Art Conventionally, when washing cook clothes in hotels and restaurants, mops in cloths or dust control fields, a large amount of articles to be washed such as large vertical batch washers and continuous washing machines are washed. A washing machine capable of being used is used.

[0003] Since this washing machine employs a system of washing by vertical rotation, as a detergent to be used, for example, a liquid laundry detergent composition containing no ethanol (JP-A-61-1668).
No. 98), a liquid detergent in a container containing a liquid detergent composition containing oleic acid in a container made of synthetic resin (JP-A-6
1-60797), a powder detergent composition for laundry prepared by combining two specific nonionic surfactants at a specific ratio (Japanese Patent Application Laid-Open No. 11-21598),
Laundry powder detergent composition containing a non-ionic surfactant as a main cleaning base and a silica-based inorganic compound having specific physical properties, a low molecular weight polycarboxylic acid, etc. (JP-A-11-2159)
No. 9) has been suitably used.

[0004] However, the detergents and the like described in these publications exhibit sufficient washing performance with respect to stains that have become diversified and heavier due to the diversification of food culture in recent years. Has become difficult. Further, with respect to mop, it is difficult to remove an oil agent mainly composed of liquid paraffin. Therefore, a detergent mainly composed of a nonylphenol type nonionic surfactant has been mainly used. The use of nonylphenol-type nonionic surfactants has been refrained from the problem of hormones and the like, and the cleaning performance using only detergents is currently insufficient.

[0005] To solve the above problem, attempts have been made to increase the amount of detergent used to improve the cleaning performance. However, simply increasing the amount of detergent used significantly increases the foaming property during cleaning. However, there is a problem in that it leads to troubles such as foam spouting from the washing machine and is extremely difficult in practical use.

On the other hand, in the washing of white goods such as shirts in the field of laundry and pillowcases of hotels in the field of linen supply, in recent years, detergents containing a nonionic surfactant as a main component have been used for the purpose of promoting high detergency. It is becoming.

However, a detergent containing a nonionic surfactant as a main component has a problem in that the ability to prevent re-adhesion of stains is not sufficient, and white goods become dull due to long-term repeated washing. In recent years, blended products of cotton and polyester have also been increasing in shirts and pillow covers, etc., especially in shirts, dirt from collar sleeves, and in pillow covers, dirt derived from sebum is difficult to remove. It is one of the factors that promote the dullness of white goods. More recently,
For the purpose of streamlining the washing process, a detergent called a one-shot in which a bleaching component is blended with a detergent has appeared. However, even if a bleaching component is blended, the above problem has not yet been fundamentally solved.

In order to solve the above problems, Japanese Patent Application Laid-Open No. 63-63795 and Japanese Patent Application Laid-Open No.
No. 9, JP-A-6-264099 and the like, studies have been made to maintain the whiteness by using a fluorescent whitening agent and an enzyme. However, since the fundamental solution such as improvement of anti-redeposition property of dirt has not yet been achieved, and the ability to remove oily dirt adhering to hydrophobic fibers such as polyester is still insufficient, it has a whiteness maintaining effect. Is not at a satisfactory level.

[0009]
